Perhaps the most extraordinary building of the nineteenth century was the Crystal Palace, which was built in Hyde Park for the Great Exhibition of 1851.
1、首先这句话是一个由which 引导的非限定性定语从句，这个定语从句的主句是一个一般过去时的简单句，结构为主系表，从句又是一个一般过去时的被动语态。
非限定性定语从句和限定性定语从句的区别--非限定性定语从句关系代词前用逗号隔开，去掉不影响主句。限定性定语从句从句与主句关系密切，不可以去掉。
2、the most extraordinary building 这是形容词的最高级
3、of the nineteenth century 介词短语做后置定语
4、Be built for为...而建造
5、Of 1851是介词短语做后置定语修饰the Great Exhibition
The Crystal Palace was different from all other buildings in the world, for it was made of iron and glass.
1、这是一个由for引导的原因状语从句，主句是一般过去时，从句也是一般过去时。
2、主句：A is different from B用来表示A不用于B
A is the same as
B A和B 一样
In the world 是介词短语做后置定语用来修饰buildings
从句：be made of & be made from 区别第一种方式：be made of可见原材料
Be made from 不可见原材料
第二种方式：be made of由一种材料制成
Be made from 由多种材料制成
It was one of the biggest buildings of all time and a lot of people from many countries came to see it.
1、这句话是由and 连接的并列句
2、Of all time “空前的史无前例的”
3、one of the biggest buildings翻译为“最大的建筑之一”
One of +可数名词复数“...之一”,这种表达比直接用形容词的最高级要委婉一些。
She is the most beautiful girl in China. She is one of the most beautiful girls in China.
4、A lot of =lots of=plenty of =a large number of =a great number of=a great many 都可以用来修饰可数名词复数
5、From many countries是介词短语做后置定语修饰people
6、To see 是动词不定时做目的状语
See可以换成visit或者call at

2、a great many =a lot of =lots of=plenty of =a large number of =a great number of 都可以用来修饰可数名词复数
而many a也表示很多，可是后面的名词要用单数。比如：
Many a student decides to take part in this long-distance race.
3、sth. Be sent to sp.(by sb.)
Someone sent a great many goods to the exhibition.
1、various parts of the world意为‘世界上的各个国家’
All parts of the world 世界各地
All over the world 世界各地
5、from various parts of the world是介词短语做后置定语修饰goods
